Part of What the 2026 podcast buying shake-up means for advertising tools and providers
Before you run a podcast advertising supplier comparison
Comparing podcast advertising suppliers in England? Score inventory access, audience data, reporting rights and rate structure before you commit budget.
What to take away
- Most teams rank suppliers on cost per thousand impressions before writing down what they are buying, which makes every quote look interchangeable.
- Compare four things instead: inventory access, targeting data, reporting rights and the commercial structure behind the rate.
- Ask which audience data each supplier will share, and whether it comes from platform reports or their own panel.
- Get the measurement terms in writing before the rate card, because reporting rights decide whether a deal is worth repeating.
Start with the brief, not the spreadsheet
A supplier comparison only works when every supplier answers the same question. Write a one-page brief covering campaign objective, target listener, episode volume, flight dates and the action you want listeners to take.
One-page campaign brief
- Campaign objective
- Target listener
- Episode volume
- Flight dates
- Desired listener action
Our podcast advertising tools and supplier guide for 2027 sets out the supplier categories in more detail if you are still deciding which partner fits the campaign.
In the UK, comparison names often include Acast, Audioboom, Global's DAX, Bauer Media and Wireless. Some are networks, some are sales houses, and some sell both.
The four columns that matter
Inventory access covers which shows or networks a supplier can actually sell, and whether that access is exclusive or resold. Ask for the show list in writing.
Targeting data covers how the supplier segments listeners. Apple Podcasts for Creators explains that subscription listening reports provide audience data for podcasts. That is a useful baseline for judging whether a supplier's targeting claims sit on top of platform data or replace it.
Reporting rights cover what you receive after the campaign and whether you can reuse it. A supplier that withholds episode-level delivery data is harder to renew.
Commercial structure covers the rate basis: fixed fee, cost per thousand impressions, tenancy or a hybrid. Two suppliers quoting the same headline number can sell very different things.
Check the market before you accept a rate
Rates move with demand, and demand moves with the wider advertising services market. The Office for National Statistics publishes business services output data covering advertising and media services. That gives you a defensible reference point when a supplier claims the market has shifted sharply in one quarter.
As a working range, UK host-read CPMs are often quoted from around £15 to £30, while programmatic audio often sits from around £5 to £15.
A six-week tenancy or sponsorship on a mid-sized UK show might start from around £2,000 to £8,000, depending on exclusivity and episode count. These are typical ranges, not fixed rate cards.
For UK audience context beyond the ONS, use Ofcom's Online Nation and Communications Market Report, RAJAR MIDAS and IPA TouchPoints. Public podcast charts can show relative reach but rarely give demographic depth.
Claims and compliance
UK campaigns sit under the CAP Code, enforced by the Advertising Standards Authority. Its guidance requires every performance claim to be substantiated before it runs. Ask for evidence behind any performance promise.
The Federal Trade Commission's notices of penalty offences are a US reference only, useful for background but not the UK test.
For a host-read slot, the host's own words are the claim. Brief them properly.
Worked example
Suppose a team in Manchester has £12,000 for a six-week campaign and three quotes on the table.
Supplier A offers a fixed fee of £11,500 for eight host-read slots across four shows, with episode-level reporting and a written show list.
Supplier B quotes £18 per thousand impressions on an estimated 700,000 impressions, so £12,600. It will not name the shows in advance and reports only aggregate platform data.
Supplier C offers a hybrid: £6,000 tenancy plus £9 per thousand impressions on a 500,000 estimate, so £10,500 if the estimate holds. It offers panel-based listener matching but no episode-level delivery.
On headline price, C wins. On certainty, A wins because the fee is fixed, the inventory is named and the reporting is defined. B depends on an estimate the team cannot verify in advance.
Our guide to podcast advertising best tools in England covers the tracking layer that makes that comparison possible.
Common questions
How many suppliers should I compare?
Three is usually enough to expose the range on rate structure and reporting. Beyond five, the marginal information drops sharply.
Should I compare on cost per thousand impressions?
Only when every supplier quotes on the same basis and the estimates come from comparable sources. Otherwise convert each quote to a fixed cost for a defined deliverable.
What should I ask for before signing?
Ask for the show list, a reporting sample, the cancellation terms and the basis of any audience estimate.
Does supplier location matter?
For a campaign aimed at listeners in England, the supplier's own location matters less than where their inventory and reporting sit.
